Which of the following is NOT a difference between normal cell division and cancer
cell division?
O Normal cells recognize signals that tell them to stop and start the cell cycle, but cancer cells
do not
Normal cells can invade other tissues, but cancer cells cannot
In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated
O Normal cells communicate with each other, but cancer cells do not
In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated. This is not a difference between normal cell division and cancer cell division. Thus, option B is correct.
What is Apoptosis?
Apoptosis is the process in which cells are destroyed or killed for the purpose of controlling their development and growth. The normal cells follow this process but the cancer cell do not response to it and keep growing.
Normal cells can invade other tissues, but cancer cells cannot. In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated.The difference between a normal cell and a cancer cell is that a normal cells undergo while cancer cells don't Also, normal cells respond to signals while cancer cells don't.
Cancer cells are grow in the absence of signals telling them to grow. Normal cells only grow when they receive such signals. Ignore signals that normally tell cells to stop dividing or to die which is the process known as programmed cell death.
Therefore, In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated. This is not a difference between normal cell division and cancer cell division. Thus, option B is correct.

every time you see the ATP starburst or lighting symbol you should relate to it which concept
Answer:
The concept must be identified: that the energy currency for cells is ATP.
Explanation:
ATP is the abbreviation of the term Adenosine Triphosphate, the presence of its three phosphors and the dephosphorylation of them are the sources of chemical and electronic energy that our body and our cells need to be able to develop life.
The following reaction occurs in each ATP molecule used for energy purposes:
ATP + KINASE ----> ADP + P (inorganic)
Kinase is the enzyme that dephosphorylates the phosphorous molecules of ATP resulting in an ADP (adenosine diphosphate) and a free inorganic phosphorus.
If the top level consumers were eliminated from a food web would the populations in the levels below them increase without bounds
Answer:
That isn't true
Explanation:
That is not true bc if the top level consumers were removed from the food chain, then the level below would become the top level of the food chain. If that happened then the level below the NEW top level of the food chain would still be getting eaten and the food chain still goes on, just with one missing level.

A piece of steel has a mass of 1170g and a volume of 150 cm3. What is the density of
steel?*
Answer:
The answer is 7.80 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass of metal = 1170 g
volume = 150 cm³
We have
[tex]density = \frac{1170}{150} = \frac{117}{15} = \frac{39}{5} \\ [/tex]
We have the final answer as
7.80 g/cm³Hope this helps you

Oxygen moves passively into our cells. Which cell will experience the slowest rate of movement of oxygen from outside the cell into the cell?
Answer:
The oxygen molecules move, by diffusion, out of the capillaries and into the body cells. While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries. Carbon dioxide is brought, through the blood, back to the heart and then to the lungs

A. Alpaca and blue whale
B. Wild boar and Angus cattle
C. Angus cattle and white-tailed deer
D. Pygmy hippopotamus and white-tailed deer
Depending on the phylogenetic tree, the two species that are most closely related are option c. Angus cattle and white-tailed deer.
Relation of two species:Angus cattle and white-tailed deer should be considered as the two species as these are closely related since it should both be taxa species that represent the close relationship in the phylogenetic tree.
Also, phgmy hippotamus and while tail dear should be less closely related as compared to the option c.
Hence, the option c is correct.

As the number of coyotes increase, the numbe

Observe the food web shown above. If the gray wolf became extinct,
what conclusion about the coyote population would not be valid
based on the relationships shown in the food web?
CLEAR ALL
Answer:
No, coyote will not become the apex predator.
Explanation:
No, coyote will not become the apex predator but greatly reduces the populations of foxes in order to reduce competition for available resources. Yes, The coyote population will decreases because t he gray wolf kills coyote to avoid competition for food resources. If another wolf is introduced to fit the same ni che, the coyote population will decrease because the wolf feeds on coyote. As the number of coyotes increase, the number of beavers will decrease because coyote feeds on beaver. If the gray wolf became extinct, the coyote population increases in that location due to no predator.
